The combination guy hook terminates guy wires or fiberglass guy strain insulators on utility poles, transferring mechanical loads through multiple mounting holes that accept bolt diameters of 5/8 inch, 3/4 inch, 11/16 inch, and 13/16 inch. This flexible configuration enables installation on round or flat surfaces across wood, steel, or concrete poles in electrical and telecommunications infrastructure.
Manufactured from ductile iron or malleable iron casting, the hook receives hot dip galvanizing per ASTM Specification A153 for corrosion resistance. This treatment protects against moisture and chemical exposure in outdoor environments, ensuring long-term durability.
Minimum ultimate tensile strength varies by model, with common ratings of 13,550 pounds, 20,050 pounds, or 21,000 pounds at a 45-degree pull angle. Some versions specify 13,500 pounds at 90 degrees to the pole. The forged or cast iron construction supports these high tensile demands when deadending guy wires with strand or fiberglass strain insulators to maintain tension and stability.
Product variations include models with or without spurs or backside cleats—spur-equipped versions grip wood poles while spurless designs suit steel or concrete. Mounting hole configurations vary, offering combinations of 11/16 inch and 13/16 inch holes or single hole sizes to match specific bolt and clevis requirements. Standard units weigh approximately 2.0 pounds per piece.
